please help me friends..

karthik

check you'r code... either there is no session for the user or you have invalidated the session already...the error you are getting, I suspect, is from the line session.isNew() and not form session.invalidate(), comment out session.invalidate() and see if you still get the exception...

just call the session and then invalidate it eg
HttpSession session = request.getSession(true);
session.invalidate();

In get request, I call a servlet , one to which i post data  String str3 =

public String getAddRequests(HttpSession paramHttpSession, HttpServletResponse paramHttpServletResponse,....

paramHttpSession.getAttribute("username").toString();

The same code works n IE but fails in firefox
